I have also followed this post and thanks to Jet I also converted over to 12 volt and never looked back..thanks for the info, it's appreciated!
Oh and I forgot to mention the 12 volt battery I'm using is a Yuasa #12N5.5-3B it was one he had off the shelf, (it has the polarity reversed from the original battery so it's installed with the terminals closer to the frame, so put a thick rubber pad against the frame to protect everything and it also keeps the battery from moving around a well!)
When I purchased the battery from my local Victory dealer he was convinced that the conversion wouldn't work! (He was convinced I was going to blow/fry every electrical component on the bike, lol)
